How to enable a complete message printing?"

The message does not provide any details for debugging the issue such as which logical symbols are involved. What can I do to resolve this error.

Solution

This error occurs when an IOB component contains a packing error. Normally, the symbols involved are listed along with the component type involved and a reason for the failure. A regression bug was introduced in ISE 11.4 where the error is printed without this important information. This problem has been fixed for ISE 12.1. Meanwhile, a more useful error messageis provided if the design is run in ISE 11.3 design tools.
